Why are houses so close to each other??

I’m not financially ready to buy a house yet, but I’ve been looking/dreaming with my husband. One thing I hate is how close houses are to each other. Neighborhoods remind me of beehives or honeycomb. I hate it! It gives me this weird feeling of like those movies where they try to force everyone to live in a utopia but it’s actually a dystopian nightmare where everyone is being controlled by the government or something. I hate it. I wanna have to squint to see my neighbors house in the distance. If I scream for help I would be okay risking my neighbors not being able to hear me for sheer distance.
